Overview
The STP40NF03L is a high-performance N-channel Power MOSFET developed by STMicroelectronics using their unique 'single feature size' strip-based process. This technology enhances the transistor's packing density, resulting in low on-resistance, rugged avalanche characteristics, and improved manufacturing reproducibility. The STP40NF03L is designed for high-current switching applications and is available in TO-220 and TO-220FP packages.
